The Orioles have officially placed three more players on the 15-day disabled list to begin the 2013 season after sending right-handed pitcher Chris Tillman there a few days ago.

Infielder Wilson Betemit (right knee ligament sprain) and pitchers Steve Johnson (right lat strain) and Tsuyoshi Wada (left elbow surgery) were sent to the DL on Sunday as the Orioles finalized their 25-man roster to begin the season. Betemit’s placement is retroactive to March 26 as the veteran hopes to return to action in six to eight weeks after suffering a torn PCL. Wada isn’t expected to return until late May or early June as he continues to rehab from last season’s Tommy John surgery.

Baltimore hopes Johnson can return soon and begin pitching for Triple-A Norfolk to begin the season after resting his back. He would be eligible to return from the disabled list next Sunday.

The club also selected the contract of outfielder Steve Pearce after he was informed by manager Buck Showalter on Saturday that he’d won the final spot on the 25-man roster.
